Electrical conductivity tester comprises a hand held unit with a single contact and a conducting housing so that an object is tested by virtue of a current flowing through the tester

摘要

The testing device for testing the current path through an electrical object (24) comprises a battery (14) and a first contact with which the testing device is placed in contact with a terminal of a test object. A person using the test object holds its conducting housing (12) in one hand and the test object in the other hand so that a current flows through their body and the test object. An amplifier in the testing device amplifies the current to activate a signaling device, e.g. an LED.
